Formula: UHMWPE, HMPE, HPPE
Form: Granule
Material: Ultra-high-molecular-weight polyethylene (UHMWPE, HMPE)
CAS Number: 9002-88-4
Commodity: Polymers
Nominal Granule Size:
2mm
Color:
Natural
UHMWPE Granules are a type of polyethylene available in 17 variations. These granules offer properties like high abrasion resistance, low friction and chemical inertness. These attributes make the UHMWPE granules suitable for applications such as bearings, gears, artificial joints and wear strips. The granular form allows the UHMWPE material to be molded into finished parts for these and other demanding applications across industrial and biomedical sectors.
